Thanks to you both for the help. I tried to do it manually by adding the extra line (as suggested by @stef.rausch) and I couldn’t get it to work. Then I tried doing as @ariehen suggested (linking to the last item in the list and then moving the ref id down two lines) and that seemed to work. I next replaced the ref id with “123456789” and it still worked. So, it is clear that the extra line is necessary. Why just adding the line it didn’t seem to work for me initially is something I can’t explain. Regardless, it now seems to work. Thanks again.
